1. Introduction to GUI Development in MATLAB
GUI development in MATLAB enables users to create interactive interfaces for performing data analysis, running simulations, controlling hardware, and more. MATLAB’s GUI development environment provides a range of tools and components for designing, building, and deploying GUI applications quickly and efficiently.
2. Getting Started with MATLAB’s GUI Development Environment
MATLAB’s GUI development environment consists of the App Designer tool, which offers a drag-and-drop interface for designing GUI layouts, adding components, and defining callbacks. Users can also create GUIs programmatically using MATLAB’s graphical functions and object-oriented programming features.
% Example of programmatically creating a GUI window
fig = uifigure('Name', 'My GUI');
btn = uibutton(fig, 'Text', 'Click Me', 'Position', [100, 100, 100, 30]);
3. Designing GUI Layouts with MATLAB’s Layout Editor
MATLAB’s Layout Editor allows users to create visually appealing GUI layouts by arranging components in a grid-based layout. Users can resize, align, and distribute components easily using the Layout Editor’s intuitive interface.
% Example of designing GUI layout with Layout Editor
